Worst experience with brand new Audi Q5 TDI 40

I bought a brand new Audi Q5 TDI 40 and took delivery on 17 September 2021. By 25 September 2021 the car started to give me problems on the instrument cluster that went completely blank and thus I could not see the speed, fuel gauge and all other important info on its virtual ****pit. The vehicle was towed to the dealership 27 September 2021....Almost a full month later, after numerous irate calls and escalations, I got the vehicle back on 26 October 2021. Fast forward to 4 December 2021, I drive the car on serious rain for the first time and then I get an error about a steering system. The car was towed to the dealership again on 07 December 2021 and after a week of diagnosis I am told that it seems like I drove the car over a steel wire that then punctured something on the steering system. This is apparently not covered by the maintenance plan and will cost me on the north of R80k to fix. How coincidental and convenient that for the first time I am driving this car in rain this issue comes out? How can I know and be sure that the damage was not delivered with the car already? This has been the worst customer experience in relation a new vehicle that I have ever gone through.

Some more info - KMs on the car - 4900 only Date of delivery - 17 September 2021 Total days of the car in my possession - 50 days Total days the car has been standing useless at the dealership - 35 and counting (as on 13 December 2021).
